Abstract— Radio Frequency Identification (RFID) is a convenient and popular concept to qualify a technology with many facets. RFID is one of the most exciting technologies that revolutionize the working practices by increasing efficiencies and improving profitability. The deployment of RFID in a large number of application areas is promising. In recent years, radio frequency identification technology has moved from obscurity into mainstream applications that help speed the handling of manufactured goods and materials. RFID technology provides a more granular visibility for industrial assets and inventory thereby offering a strategic advantage to the business. This paper introduces the basic mechanism of RFID technology, effectively addressing security and privacy issues in the short term. Finally, we discuss several challenges and obstacles to RFID adoption, as well as emerging technologies relevant to RFID.

Radio Frequency Identification (RFID) was first developed during World War II in order to distinguish between friend and enemy aircraft. Although the foundation of RFID technology was laid by past generations, only recent advances opened an expanding application range to its practical implementation. RFID is one of numerous technologies grouped under the term Automatic Identification (Auto ID), such as bar code, magnetic inks, optical character recognition, voice recognition, touch memory, smart cards, biometrics etc. Auto ID technologies are a new way of controlling information and material flow, especially suitable for large production networks.

The RFID technology is a means of gathering data about a certain item without the need of touching or seeing the data carrier, through the use of inductive coupling or electromagnetic waves. Bar code technology uses light as the transmission media, while RFID systems use radio waves. A technology that is mature enough to be mass-marketed at competitive cost and become a critical player in the global market.

Principle

The basic function of an RFID system is to automatically retrieve the information that has been previously inserted into specific integrated circuits. The data carrier is a microchip attached to an antenna (together called transponder or tag), the latter enabling the chip to transmit information to a reader (or transceiver) within a given range, which can forward the information to a host computer. The middleware (software for reading and writing tags) and the tag can be enhanced by data encryption for security-critical application at an extra cost, and anti-collision algorithms may be implemented for the tags if several of them are to be read simultaneously.

The most important differentiation criteria for RFID systems are the operating frequency of the reader, the physical coupling method and the range of the system. RFID systems are operated at widely differing frequencies, ranging from 135 kHz longwave to 5.8 GHz in the microwave range. Electric, magnetic and electromagnetic fields are used for the physical coupling. Finally, the achievable range of the system varies from a few millimeters to above 15 m.

Transponders contain RAM, ROM, EEPROM* or FRAM* and an HF interface to provide the power supply and permit communication with the reader.

RFID Technology in a Healthcare Setting
Radio-frequency identification (RFID) is an emerging technology that can be applied to a variety of disciplines to track inventory, manage personnel, identify data elements, as well as perform many other tasks or services. Any basic RFID system consists of a tag, a reader, and software which can be used to interact with the RFID device. This software filters, aggregates, and uses the RFID data to support that organization’s day to day functions. The premise is certainly not new technology, but rather a technological advancement of bar-coding. Recently, RFID technology has found its way into the healthcare setting, particularly in the field of medical records. Although in its infancy, RFID technology has a shown great potential to considerably reduce cost, increase patient safety, and improve the quality of care. Although it has many uses in a healthcare organization, this paper will focus on RFIDs and the medical record. The focus of this report will be on the uses, issues, and impacts of the human implantable RFID chip and the traditional RFID system.
The first reported RFID implant was in 1998 in Britain by scientist Kevin Warwick. As part of his experiment, Warwick used his implant to open doors, switch on lights, and cause a verbal...

Abstract
Radio Frequency Identification (RFID) is one of the most exciting technologies that revolutionize the working practices by increasing efficiencies, and improving profitability. It is often presented as a replacement for today’s barcodes, but the technology has much greater possibilities, such as individual serial numbers for each item, and the possibility to read these numbers at a distance of several meters. They are simpler to deploy than wired solutions and these networks will enable improved understanding
of processes and environments through continual monitoring of a larger set of parameters.
In this project the evolution of wireless sensor networks will be presented, using RFID techniques with examples of implementations in payment of certain items without using the Universal Product Code (UPC). A virtual database comprising of RFID tags, antennae and experimental setup will be
created and verified to make sure the proper amount is deducted from the correct item. The project I want to implement will fetch added features like speed in transaction, cost efficiency, low frequency of errors, etc. Another added feature will be the accuracy of the data recorded. Human errors will be resolved to the maximum thereby improving the efficiency of the system. The old-fashioned...

A RFID BASED LIBRARY MANAGEMENT SYSTEM
1. Introduction
B Library is a growing organism. As it grows in size the problems associated with the maintenance and security of the documents also grows (Narayanan et al., 2012). To solve the problems of arranging and searching documents, books, space and time librarians used different techniques (e.g., bar-codes) to digitize the documents and share over network. Bar-codes have served the librarians and libraries for a long time, and now it is getting replaced by RFID (Radio Frequency IDentification).
C Radio frequency identification (RFID) falls under the category of automatic data collection (ADC) technologies. It is used to describe a system that transfers the identity of an object or person wirelessly, using radio waves. RFID was invented in 1969, patented in 1973, first used in harsh industrial environment in 1980s’, and standards were presented in 2001. It is the latest addition of technology to be used in the libraries for a combination of automation and security activities in the well maintenance of documents either inside the library or goes out-of library.

...RFID TAGS
Introduction
Over time, the ways products have been tracked through the supply chain have changed just as technology is constantly progressing. Yet, there are still constraints to improve the methods of tracking and shipping due to the lack of technology in these fields. Bar codes have helped but still need human interference. Many companies are starting to turn to radio frequency identification tags. RFID tags can help companies with tracking and shipment of any product and reduce time to improve customer satisfaction. (Wolff, 2001) Companies such as IBM who are producing the tags have started to think of ideas to revolutionize this plan. The RFID tags can help track products as they enter and leave warehouses, and can speed up the shipping process. They can be put into different products and even use them in such ways as at the grocery store instead of having cashiers and cash registers. (Wolff, 2001) The superstore, JC Penney, is interested in taking advancements with the RFID tags. These tags are programmable and cannot get damaged like barcodes can. In the 21st century, we are constantly moving forward with such innovations. The RFID tags are currently in use by some companies already, and being modified by others for their particular needs. These tags could open doors for many new inventions and help us progress into a faster-moving and progressing world.
